Dhurandhar (2025) and its sequel are espionage action films based on a fictionalized narrative heavily inspired by real-world, covert intelligence operations conducted by India's R&AW and IB against terror networks in Pakistan. While often marketed as "inspired by true events," the films are largely fictional, focusing on themes like the 26/11 attacks and underworld networks rather than a single true story. 

Key Real-World Inspirations & Elements:

• Intelligence Operations: The plot revolves around covert, cross-border counter-terrorism operations, similar to those aimed at identifying handlers and financiers of terror outfits in Pakistan.
• Key Incidents:
   The narrative is structured around major real-life events, including the 1999 Kandahar hijacking (IC-814), the 2001 Indian Parliament attack, and the 2008 Mumbai attacks.
Inspiration for Characters: R. Madhavan's character (IB Director Ajay Sanyal) is reportedly fashioned after Ajit Doval, India’s National Security Advisor.
Alleged Operations: The film is believed to draw inspiration from Operation Lyari, a long-term crackdown on criminal gangs in Karachi.
Fiction and Myth: Despite rumors, the main character played by Ranveer Singh is not based on the late Army officer Major Mohit Sharma; the filmmakers clarified this, and the film includes a disclaimer stating it is a work of fiction. 

The film focuses on the intense, often "underworld-infiltrating" style of spying, blending high-stakes action with political drama.
